Many of the walls areincomplete, which fact shows the communication between the cavity walls are lined by endothelium. Cavernous hemangiomataare sometimes called erectile tumors, owing to their resemblance toerectile tissues, such as the corpus cavernosum of the penis. Theyare rarely congenital, and may develop from pre-existing simple hem-angioma. Usually they occur early in life, and are rare in old this form of tumor develops in the skin and forms a livid, raised,and uneven patch, it is referred to as a nevus prominens. Angiomata are common in the skin and subcutaneous tissue, andoccasionally are observed in the liver. They may occur in the kidney,spleen, uterus, intestines, bladder, voluntary muscle, bone, mamma,tongue, larynx, subperitoneal tissue—in fact, in almost any vasculartissue. -- A. ^A^^- Fig. iqi.—Cavernous Hemangioma from the Wall of Branchial Comeus stratum.

Plexiform Hemangioma (Racemose Aneurysm, Aneurysm byAnastomosis, Cirsoid Aneurysm).—Properly, this is not a neoplasm,but a pathologic alteration of the affected vessels. The vessels becomedilated and convoluted, and, by pressure on the intervening tissue,cause atrophy. The vessel-walls are usually thickened. The tumormay be congenital or acquired. When occurring in the most super-ficial vessels, it is, by some, called a nevus vascvilosiis. Plexiformangioma sometimes follows injury. It usually involves the scalp(frontal and temporal re
